QGIS Environmental Spatial Analysis and Impact Mapping Training Course

Course overview

Environmental managers and HSE teams are regularly asked to demonstrate where sensitive receptors, operational activities and environmental risks overlap. Static maps and spreadsheet-based assessments make it difficult to justify buffer distances, compare site alternatives, identify cumulative impacts or communicate findings to regulators and project stakeholders. This course equips participants to use QGIS to turn environmental monitoring, land-use, biodiversity, emissions, incident and infrastructure data into defensible spatial evidence for planning, permitting, compliance and impact assessment.

Participants build practical capability in QGIS data management, coordinate reference systems, vector and raster analysis, proximity and overlay methods, terrain and hydrological analysis, weighted suitability modelling, and impact-receptor mapping. They learn to prepare spatial datasets from field, regulatory and corporate sources; calculate exposure zones; analyse constraints; classify environmental sensitivity; and create clear map outputs that support Environmental Impact Assessments (EIAs), site selection studies, emergency planning and environmental management plans.

The course is delivered through instructor-led demonstrations followed by guided QGIS workflows using realistic environmental datasets. Exercises include protected-area screening, contaminated-land buffer analysis, watershed delineation and multi-criteria site suitability assessment. By the end of the week, each participant produces a documented environmental impact mapping project: a QGIS project file, analysed spatial layers, map layouts and a concise methods note explaining data sources, assumptions, analysis steps and limitations.

It is designed for environmental practitioners who already work with maps or environmental datasets and need a reliable, repeatable QGIS workflow for operational decisions and formal environmental reporting.

Course objectives

By the end of this course, participants will be able to:

• Configure a QGIS project with appropriate coordinate reference systems, layer naming conventions and environmental data metadata
• Prepare vector datasets using attribute joins, field calculations, geometry checks and spatial data cleaning tools
• Create impact-receptor zones using buffers, intersections, spatial selections and overlay analysis
• Analyse elevation, slope, aspect and drainage patterns from digital elevation models using QGIS terrain tools
• Classify and reclassify raster environmental data for sensitivity screening and suitability modelling
• Build a weighted multi-criteria site suitability model using raster calculator expressions and documented scoring rules
• Produce regulator-ready impact maps with scale bars, legends, labels, symbology, map grids and print layouts
• Document an environmental spatial analysis workflow in a QGIS project package and concise methods note

Benefits of attending

Target competencies

Who should attend

• Environmental Officers — who need to map compliance risks, monitoring locations and environmental constraints
• HSE Managers — who need spatial evidence to prioritise controls and communicate site risks
• Environmental Consultants — who prepare impact assessments, baseline studies and permitting submissions
• EIA Practitioners — who must assess project footprints against sensitive environmental receptors
• GIS Analysts — who support environmental teams with repeatable spatial analysis workflows
• Sustainability and ESG Specialists — who need location-based evidence for land, water and biodiversity reporting

Requirements and prerequisites

Participants should be comfortable working with environmental datasets in spreadsheets or GIS tables and should understand basic map concepts such as layers, attributes, scale and coordinate systems. Prior exposure to QGIS, ArcGIS or another desktop GIS is strongly recommended, including opening layers and navigating a map canvas. Familiarity with common environmental terms such as receptors, buffers, catchments, land cover and protected areas will help. Participants do not need programming, database administration, advanced statistics, remote-sensing expertise or prior experience with QGIS processing models. A laptop capable of running QGIS is required for live online delivery.

Training methodology

Each day combines short instructor-led demonstrations with structured QGIS lab work using environmental datasets such as protected areas, land cover, emissions sources, watercourses, monitoring points and digital elevation models. Participants work through individual analysis tasks, then compare assumptions and map interpretations in small-group review sessions. Case exercises mirror EIA screening, contaminated-land assessment and site-selection decisions. On the final day, participants assemble an end-to-end impact mapping workflow and identify how the same methods, datasets and quality checks can be applied to a current workplace project.

Course outline

Day 1: Environmental GIS foundations in QGIS

• QGIS interface, Browser panel and project organisation for environmental work
• Coordinate reference systems and projection choices for area and distance analysis
• Environmental data formats including GeoPackage, GeoJSON, shapefile, CSV and web services
• Importing monitoring coordinates and tabular environmental records
• Attribute table management, field types and environmental data dictionaries
• Geometry validation, duplicate removal and missing-value checks
• Layer styling for receptors, sources, monitoring points and management zones

Workshop: Participants prepare a clean QGIS project containing operational sites, monitoring locations, protected areas and watercourse receptor layers with documented metadata.

Day 2: Vector impact and constraint analysis

• Buffer analysis for emissions sources, spill locations and regulated setback distances
• Dissolve and multipart tools for consolidated impact zones
• Clip, intersect, union and difference overlays for footprint assessment
• Spatial selection by location for receptor screening
• Distance-to-nearest calculations for sensitive environmental features
• Field Calculator expressions for area, length and impact-category metrics
• Summarising affected receptors by administrative area and project phase

Workshop: Participants create an impact-receptor screening map and tabulated summary for a proposed industrial facility footprint.

Day 3: Raster, terrain and catchment analysis

• Raster data properties, resolution and alignment in environmental interpretation
• Loading and inspecting digital elevation models in QGIS
• Slope, aspect, hillshade and elevation classification tools
• Raster clipping and resampling for a defined study boundary
• Hydrological flow direction and flow accumulation concepts
• Catchment and drainage-risk interpretation from terrain surfaces
• Raster Calculator expressions for environmental threshold mapping

Workshop: Participants derive terrain and drainage-risk layers from a digital elevation model and identify runoff pathways toward downstream receptors.

Day 4: Sensitivity and site suitability modelling

• Environmental sensitivity criteria and transparent scoring frameworks
• Raster reclassification of land cover, slope, proximity and protected-area constraints
• Weighted overlay methodology for site suitability assessment
• Normalising criteria values and documenting weight assumptions
• Masking exclusion areas and no-go zones
• Comparing alternative site locations using zonal statistics
• Sensitivity testing of weights and threshold values

Workshop: Participants build a weighted suitability model that ranks three candidate sites and records the rationale for criteria and weights.

Day 5: Impact map production and reproducible reporting

• Map design principles for environmental assessment audiences
• Categorised, graduated and rule-based symbology for impact communication
• QGIS Print Layouts, map frames, legends, scale bars and north arrows
• Atlas generation for multiple sites or management areas

• QGIS Processing Modeler for repeatable impact-screening workflows
• Packaging QGIS projects and exporting PDF, image and geospatial deliverables

Workshop: Participants complete and present an environmental impact mapping package comprising a QGIS project, final map layout, analysis outputs and methods note.
